I am from Minehead.
To relive boredom i have tried rigid 29er down fort william and raced down Glencoe.
You will be fine on a full susser. If you have some ability in your riding, rigid, HT, short travel susser will ramp up some excitement.
The Knights of Klunk used the area for a reason……….
There is no right or wrong bike, just the bike you have on that day, from epic xc to technical DH it’s all there (and the Quantocks too)
Nearest bikeshop is Pompeys in Minehead (say hello to Tim the mechanic)
Maybe don’t try to ride through the harbour, the mud is deep and smelly 🙂
Enjoy.
